However, unfortunately it is not efficient in some situations. So many researchers have tried to solve these inefficiencies. In this way, Revised Theory of Constraints is proposed to use the advantage of this method for certainty conditions . </i></p><i>Nevertheless, in the real world situations many parameters such as processing time, capacity and profit are not completely certain. Furthermore, Fuzzy set theory has been used to model systems that are hard to define precisely and represents an attractive tool to aid research in production management when the dynamics of the production environment limit the specification of model objectives, constraints and the precise measurement of model parameter. So In this paper, an algorithm based on RTOC and fuzzy logic is proposed. The results have shown this algorithm is an effective and flexible algorithm </i>. تئوری محدودیت‌های اصلاح شده (RTOC)،ترکیب تولید، زمان پردازش فازی،ظرفیت فازی،سود فازی Product mix,Theory of constraints,Fuzzy linear programming,Fuzzy processing time, Fuzzy capacity,Fuzzy profit 359 368 http://ijiepm.iust.ac.ir/browse.php?a_code=A-10-1-156&slc_lang=fa&sid=1 ناصر حمیدی، nhamidi1344@gmail.com 180031947532846003580 180031947532846003580 Yes استادیار دانشکده مدیریت و حسابداری دانشگاه آزاد اسلامی قزوین پروانه سموئی، samouei_parvaneh@yahoo.com 180031947532846003581 180031947532846003581 No مدرس دانشکده مدیریت و حسابداری دانشگاه آزاد اسلامی قزوین مهدی اقبالی، 180031947532846003582 180031947532846003582 No دانش‌آموخته مهندسی صنایع
